Title: Effective length measurement of endless cone belt - derived from angular position error of belt under slipless, torqueless drive
Inventor: SCHLEIERMACHER HERBERT
IPC: G01B5/02
Filed: 1979-06-07
Abstract: An arrangement for measuring the effective working length of an endless narrow cone belt uses two rotary measurement belt discs applying a constant tension to the belt under test. They enable accurate effective length measurement via an effective breadth measurement independent of the disc sizes. The effective length is derived from an effective breadth dimensional error. The cone belt discs form a belt drive system of known gear ratio. The breadth error is determined from the measured gearing error using a non-slip torqueless drive. The gear ratio error is measured indirectly from a belt drive rotation angle deviation using a formula including the cone angle of the belt and a measurement disc effective dia.

Title: Alcohol removal from fermented drinks - by dialysis at low differential pressure
Inventor: GARSKE FRIEDRICH ING GRAD
IPC: C12H1/16
Filed: 1979-09-07
Abstract: Prodn. of fermented drinks (e.g. beer or wine) with a reduced alcohol content is carried out by dialysing a conventionally produced fermented drink at a differential pressure of 5 (pref. 1, esp. 0.1) bar. The drink is pref. dialysed against an alcohol-free drink of the same type, in which case the alcohol is removed from the dialysate (e.g. by adsorption, extraction, reverse osmosis and/or distn.) and the alcohol-free dialysate is recycled. In the case of CO2-contg. drinks, the pressure at which dialysis is carried out should be greater than the satn. pressure of the dissolved CO2, and the drink is pref. dialysed against a liq. contg. the same amt. of CO2 as the drink. Dialysis is more selective than reverse osmosis (cf. DT 2135938), so that alcohol can be removed without significantly altering the flavour of the drink.

Title: Blood dialysis equipment with balancing chamber - which is divided by two impermeable membranes with detector to indicate rupture
Inventor: MAHN DIETER
IPC: A61M1/16
Filed: 1980-04-30
Abstract: In the blood circuit, blood purified of products of metabolism is conveyed by a pump. The dialysate circuit contains a balancing chamber (1) divided into two part chambers separated by an impermeable membrane to form an hydraulically coupled connection. These chambers are alternately filled with and emptied of fresh or used dialysate and ultrafiltrate can be removed from this closed system by an ultrafiltrate pump, a dialysator connected with the dialysate circuit and the blood circuit. In the balancing chamber (1) there are at least two membranes (6a,6b) with a detector (22,23) for recognising a rupture of a membrane. The space (29) between the spaced-apart membranes may be evacuated to bring them together. Alternatively, it may be filled with an incompressible medium which keeps them apart. In particular, this medium may be a liquid having a different electrical conductivity from the dialysate. The detector system may comprise electrodes (22,23) connected to a voltage source (24) and indicator (25). With this arrangement, the electrodes respond to specific ions contained in the dialysate. In a variant, the detector responds to changes in the light conductivity in the chamber (29) of the liquid contained there, esp. containing a dissolved dye.
